This occurs when using Windows 10 Virtual Desktops through the Task View. If you have a CWC session open and on you second Virtual Desktop as the focused Window. When you attempt to use the hotkey (Win + ArrowKey) to switch to that Desktop the Windows key acts like it is "held" down so any keystrokes act like hotkey on my computer. I have to click off the CWC session then click the Windows key again to "release" it.
